Background: Takotsubo cardiomyopathy (TTC) has been historically considered a contraindication for heart donation due to its transient left ventricular dysfunction. However, emerging evidence supports that hearts from donors with fully recovered Takotsubo Cardiomyopathy can be safely transplanted. Methods: This case series describes seven heart transplantations performed between January 2022 and September 2025 using donors with previously diagnosed Takotsubo cardiomyopathy. Donor characteristics, intraoperative data, echocardiography data and postoperative outcomes were analyzed. Results: The mean donor age was 33.5 years (range 18–58), with a male-to-female ratio of 6:1. All donors exhibited echocardiographic evidence of Takotsubo Cardiomyopathy at the time of brain death, with full or partial recovery before procurement. Coronary angiography excluded obstructive coronary disease. Echocardiographic follow-up demonstrated the mean LVEF increased to 52 ± 6%, reaching 58 ± 4% at 12 months, global longitudinal strain (GLS) improved progressively (from −14.2 ± 2.8% to −18.5 ± 1.9%), confirming normalization of myocardial deformation and the right ventricular function, assessed by TAPSE, rose from 15 ± 3 mm at discharge to 20 ± 2 mm at 12 months. All patients transplanted with donors who had Takotsubo cardiomyopathy are alive at the 12-month follow-up. Conclusions: Hearts from donors with resolved Takotsubo Cardiomyopathy can be safely used for transplantation without compromising early- or mid-term outcomes. Expanding donor eligibility criteria to include selected TTC donors may contribute to mitigating organ shortages in advanced heart failure patients.

Atrial dilated cardiomyopathy with progression to atrial standstill is an ultrarare arrhythmogenic disorder characterized by complete loss of atrial electrical and mechanical activity. This condition, which may occur sporadically or in familial clusters, is associated with a markedly increased thromboembolic risk. The electrocardiographic hallmark is the absence of P waves combined with a bradycardic junctional escape rhythm. Biatrial enlargement gradually evolves into giant atria with preserved biventricular systolic function, while supraventricular arrhythmias and progressive atrial inexcitability dominate the clinical course. Valvular regurgitation frequently worsens in parallel with atrial remodelling, and patients often require permanent pacemaker implantation as well as lifelong anticoagulation. Among the few genetic determinants identified, the homozygous c.449G>A (p.Arg150Gln) mutation in the Natriuretic Peptide A gene represents one of the best characterized mechanisms. Disertori et al. first reported this pathogenic variant in 13 affected individuals from Italian families, establishing a recessive inheritance pattern. More recently, Silva et al. and Forleo et al. described additional cases, expanding the phenotypic spectrum of NPPA-related atrial cardiomyopathy. These findings confirm that homozygous carriers develop a severe atrial phenotype, whereas heterozygous relatives typically remain asymptomatic, underlining the importance of genetic testing in young patients with unexplained atrial fibrillation or standstill. Recognition of atrial cardiomyopathy as a distinct clinical entity is crucial, since early diagnosis may guide timely anticoagulation, arrhythmia management, and tailored follow-up. Broader adoption of genetic screening in patients with isolated atrial dysfunction could support precision medicine approaches, improve risk stratification, and ultimately prevent adverse outcomes in this ultrarare but highly morbid condition.

Background/Objectives: Retained fragments of cardiovascular implantable electronic device (CIED) leads are frequently observed after orthotopic heart transplantation (OHT), but their clinical relevance remains unclear. Methods: We conducted a single-center, retrospective study of 179 adult patients who underwent OHT between January 2022 and January 2025. Post-transplant imaging was used to identify retained lead fragments. Patients were grouped based on the presence or absence of retained leads. The primary endpoint was all-cause mortality at 30, 90, and 150 days post-transplant. Survival analysis was performed using Kaplan–Meier estimates and Cox proportional hazards modeling. Results: Among 112 patients with pre-transplant CIEDs, 18 (16%) had retained intravascular lead fragments. These patients had significantly lower survival at 30 days (66.7% vs. 94.7%), 90 days (61.1% vs. 90.3%), and 150 days (55.0% vs. 83.5%) compared to those without retained fragments (log-rank p = 0.002). The presence of retained leads was independently associated with increased mortality (HR: 3.71; 95% CI: 1.55–8.84; p = 0.003), even after adjusting for potential confounders. Conclusions: Retained CIED lead fragments are independently associated with higher early post-transplant mortality. These findings support the need for individualized intraoperative strategies to mitigate hardware-related risks in high-risk transplant candidates.

Hypertrophic cardiomyopathy (HCM) is a cardiac disorder characterized by unexplained left ventricular hypertrophy and a clinical presentation that is heterogeneous, ranging from asymptomatic cases to sudden cardiac death (SCD). The condition’s complex pathophysiology encompasses myocyte disarray, fibrosis, and impaired cellular metabolism. Advancements in non-invasive cardiac imaging, notably echocardiography and cardiac magnetic resonance (CMR), have led to substantial progress in the domains of early diagnosis, phenotypic characterization, and risk stratification. Echocardiography is the preferred diagnostic modality, as it provides a comprehensive evaluation of ventricular hypertrophy patterns, left ventricular outflow tract (LVOT) obstruction, mitral valve abnormalities, left atrial size, and diastolic function. Novel techniques, such as speckle-tracking strain imaging, have emerged as means to detect subclinical myocardial dysfunction and to provide significant prognostic information. Cine-CMR sequences, tissue characterization with late gadolinium enhancement, and quantitative techniques such as strain imaging have been shown to enhance diagnostic precision and prognostic evaluation. The integration of multimodality imaging has been demonstrated to enhance the management of patients with HCM, both in the short term and in the long term, by facilitating individualized monitoring. This review summarizes the role of cardiac imaging in the comprehensive evaluation of HCM, emphasizing the impact of these methods on diagnosis, risk assessment, and personalized patient care, particularly in challenging clinical settings, such as cases of athlete’s heart and pathological ventricular hypertrophy.

Background/Objectives: Heart transplantation (HTx) is a lifesaving procedure for end-stage heart failure patients; however, postoperative infections remain a major challenge due to immunosuppressive therapy and surgical complications. Traditional biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT) have limitations in distinguishing infections from systemic inflammatory response syndrome (SIRS). Emerging markers such as Presepsin and interleukin-6 (IL-6) may improve diagnostic accuracy. This study aimed to evaluate the kinetics and reliability of these four inflammatory biomarkers in heart transplant recipients in the immediate postoperative period. Methods: This retrospective observational study included 126 patients who underwent HTx at Policlinic of Bari between January 2022 and November 2024. Patients were categorized into infected (n = 26) and non-infected (n = 100) groups based on clinical and microbiological criteria. Biomarkers (CRP, PCT, Presepsin, and IL-6) were measured preoperatively and on postoperative days (PODs) 1, 2, 3, 4, 5, and 10. Statistical analyses included the Mann–Whitney U test and logistic regression to identify the independent predictors of infection. Results: CRP and PCT levels differed significantly between the groups only on day 10, limiting their use as early infection markers. In contrast, Presepsin levels were significantly elevated in infected patients from day 1 (p < 0.001), whereas IL-6 levels showed significant differences from day 3 onward. Presepsin showed the strongest association with infection in the early postoperative phase. Conclusions: Presepsin and IL-6 outperformed CRP and PCT in detecting early postoperative infections in heart transplant recipients. Their early elevation supports their use as reliable markers for guiding timely clinical intervention and improving patient outcomes. Further research is needed to validate these findings in larger cohorts and with different immunosuppressive regimens.

Gender-specific cardiology has gained increasing recognition in recent years, emphasizing the need for tailored management strategies for women with cardiovascular disease. Among these, cardiomyopathies—dilated, arrhythmogenic, hypertrophic, and restrictive—pose unique challenges throughout a woman’s reproductive life, affecting contraception choices, pregnancy outcomes, and breastfeeding feasibility. Despite significant advances in cardiovascular care, there is still limited guidance on balancing maternal safety and neonatal well-being in this complex setting. This review provides a comprehensive overview of the current evidence on reproductive counseling, pregnancy management, and postpartum considerations in women with cardiomyopathies. We discuss the cardiovascular risks associated with each cardiomyopathy subtype during pregnancy, highlighting risk stratification tools and emerging therapeutic strategies. Additionally, we address the safety and implications of breastfeeding, an often overlooked but increasingly relevant aspect of postpartum care. A multidisciplinary approach involving cardiologists, gynecologists, obstetricians, and anesthesiologists is crucial to optimizing maternal and fetal outcomes. Improved risk assessment, tailored patient counseling, and careful management strategies are essential to ensuring safer reproductive choices for women with cardiomyopathy. From now on, greater attention is expected to be given to bridging existing knowledge gaps, promoting a more personalized and evidence-based approach to managing these patients throughout different stages of reproductive life.

Bicuspid aortic valve (BAV) is the most common congenital heart anomaly, affecting an estimated 0.5% to 0.77% of the general population. This condition occurs when the aortic valve has only two cusps instead of the usual three, disrupting normal valve function and increasing the risk of various cardiovascular diseases. Often asymptomatic in its early stages, BAV can gradually progress, leading to stenosis, valve insufficiency, and abnormalities of the ascending aorta. One particularly concerning aspect is its potential association with sudden cardiac death (SCD). The aim of this literature review is to examine the relationship between BAV and the risk of SCD, highlighting the pathogenic variants and pathophysiological mechanisms involved while emphasizing the significance of valve classification and its clinical implications. Additionally, it explores current research gaps and future directions to enhance early identification of at-risk individuals and reduce the incidence of SCD.

Acute coronary syndrome (ACS) and stroke are interconnected conditions that often share risk factors such as atherosclerosis, thrombosis, and systemic inflammation. When these events occur simultaneously, they present unique diagnostic and therapeutic challenges. This review explores the pathophysiological mechanisms linking ACS and stroke, including common pathways like plaque instability, cardioembolism, and endothelial dysfunction, while highlighting the distinct features of ischemic and hemorrhagic strokes. The manuscript provides an overview of diagnostic strategies, emphasizing the role of biomarkers, advanced neuroimaging, and risk stratification tools in guiding acute management. Furthermore, the review delves into treatment approach, emphasizing the need to balance reperfusion therapies for ACS with thrombolysis or thrombectomy for ischemic stroke while carefully managing the challenges posed by anticoagulation in cases complicated by bleeding. Long-term strategies for secondary prevention are examined, including antithrombotic regimens tailored to the dual risk of thrombosis and bleeding, as well as lipid-lowering and blood pressure management. Future perspectives highlight the potential of novel pharmacological agents, neuroprotective therapies, and AI-driven tools to enhance patient outcomes. This review underscores the importance of integrated, multidisciplinary care and identifies key areas for future research to optimize the management of these high-risk patients.

Hypertrophic cardiomyopathy (HCM) is a condition characterized by left ventricular hypertrophy, with physiopathological remodeling that predisposes patients to atrial fibrillation (AF). The electrocardiogram is a basic diagnostic tool for evaluating heart electrical activity. Key electrocardiographic features that correlate with AF onset are P-wave duration, P-wave dispersion, and electromechanical delay in left atrium (LA). Clinical markers, including age, body mass index, New York Heart Association functional class, and heart failure symptoms, are also strong predictors of AF in HCM. Risk scores have been created using multiple variables to better predict AF development. Increasing knowledge of genetic subsets in HCM and cardiovascular pathology in general has provided novel insight in this context. Structural and mechanical LA remodeling, including fibrosis, altered LA function, and changes in atrial size, further contribute to AF risk prediction. Cardiovascular magnetic resonance (CMR) and echocardiographic measures provide accurate information about atrial structure and function. Machine learning models are increasingly being utilized to refine risk prediction, incorporating a wide range of variables. This review highlights the multifaceted approach required to understand and predict AF development in HCM. Such an approach is imperative to enhance prognostic accuracy and improve the quality of life of these patients. Further research is necessary to refine patient outcomes and develop customized management strategies for HCM-associated AF.

Background: Several drugs are emerging as potential therapeutic resources in the context of chronic heart failure (CHF), although their impact on daily clinical practice remains unknown. The objective of this study was to investigate the theoretical eligibility for vericiguat and omecamtiv mecarbil (OM) in a real-world outpatient setting. Methods: A cross-sectional observational study was conducted, enrolling all patients with CHF who had at least one visit between January 2023 and January 2024 in a dedicated outpatient clinic of a tertiary referral center. Theoretical eligibility for vericiguat and OM in our population was assessed by adopting the criteria of the respective phase III clinical trials (VICTORIA trial for vericiguat and GALACTIC-HF trial for OM). Results: In 350 patients with CHF, the rate of individuals eligible was 2% for vericiguat and 4% for OM. A value for left ventricular ejection fraction (LVEF) over the clinical trials’ cutoffs was observed in 41% of cases for vericiguat and 69% for OM. The absence of a recent heart failure (HF) worsening was found in 78% of cases for vericiguat and 72% for OM. Conclusions: Only a small proportion of CHF patients would be eligible for vericiguat and OM in a real-world outpatient setting. The absence of a recent HF worsening and an LVEF over the established trials’ cutoffs are the main causes of non-eligibility. Further studies are required to assess the efficacy of these drugs in a wider population in order to increase the candidates for these beneficial treatments.
